[0023] Please refer to Figure 1 , Figure 2 and Figure 3 , in the embodiment of the present utility model, the end connecting piece of the P2 system includes: a first connecting piece 1 and a second connecting piece 2. An inner connecting cylinder 103 is slidably arranged on the outer side of one end of the first connecting piece 1. An outer fixed ring plate 101 is fixedly arranged on the outer side of one end of the first connecting piece 1. A pull-back spring 102 is fixedly arranged between the outer fixed ring plate 101 and the inner connecting cylinder 103. An outer screw sleeve 3 is rotatably arranged on the outer side of one end of the second connecting piece 2. The outer screw sleeve 3 is in threaded cooperation with the inner connecting cylinder 103 for quickly connecting the first connecting piece 1 and the second connecting piece 2. A locking assembly 4 is arranged on the outer side of the outer screw sleeve 3. An inner connecting end cylinder 104 is fixedly arranged at one end of the first connecting piece 1 and the inner connecting cylinder 103. An end ring step is fixedly arranged on the outer side of the inner connecting end cylinder 104. A sealing gasket 105 is fixedly arranged on the end face of the end ring step.
[0024] Rotate the outer screw sleeve 3 so that the inner connecting cylinder 103 can move on the outer side of the first connecting piece 1 and slowly enter the inner side of the outer screw sleeve 3. At the same time, the inner connecting end cylinder 104 will enter the inner side of the second connecting piece 2 until the sealing gasket 105 contacts the outer screw sleeve 3, so that a certain sealing performance can be achieved between the first connecting piece 1 and the second connecting piece 2, facilitating the flow of the coolant. It should be noted that after the inner connecting cylinder 103 enters the outer screw sleeve 3, one end of the inner connecting cylinder 103 is flush with one end of the first connecting piece 1. At this time, the pull-back spring 102 is in an extended state, providing a pulling force to the inner connecting cylinder 103 to prevent the inner connecting cylinder 103 from loosening, so that too many bolts and too many parts do not need to be assembled on site, improving the installation efficiency.
[0025] Refer to Figure 1 , Figure 2 and Figure 4, an annular slide rail 301 is fixedly arranged on the outer side of the outer sleeve 3. The cross-section of the annular slide rail 301 is in a "T" shape. A locking notch 1011 is formed on the outer side of the outer fixed ring plate 101. The edges of both end faces of the first connecting piece 1 are arranged in an inclined plane. The locking and connecting assembly 4 includes a connecting long frame 401. The connecting long frame 401 is slidably arranged on the outer side of the annular slide rail 301. One side of the top end of the connecting long frame 401 penetrates and is slidably provided with a first vertical slide rail 402. One side of the bottom end of the first vertical slide rail 402 is fixedly provided with a locking block 403. The top end of the locking block 403 is fixedly provided with a vertical slide rod 404 and a return spring 405. The return spring 405 is fixedly arranged at the bottom end of the connecting long frame 401. The vertical slide rod 404 penetrates and is slidably arranged at the bottom end of the connecting long frame 401. The other end of the vertical slide rod 404 is fixedly provided with a handle 406. One side of the bottom end of the locking block 403 is arranged in an inclined plane. The other side of the locking block 403 is fixedly provided with a second vertical slide rail 407. One side of the top end of the second vertical slide rail 407 is fixedly provided with a return spring 408. The other end of the return spring 408 is fixedly provided with a hook locking block 409. The hook locking block 409 is slidably arranged on one side of the second vertical slide rail 407. One side of the bottom end of the hook locking block 409 is arranged in an inclined plane. The locking block 403 is clamped inside the locking notch 1011 in the connected state.
[0026] When the hook locking block 409 in the locking and connecting assembly 4 contacts the outer fixed ring plate 101 and rises upward, the return spring 408 is compressed. As the second connecting piece 2 moves, the hook locking block 409 moves to the other end face of the outer fixed ring plate 101. At the same time, the handle 406 is lifted upward, so that the locking block 403 rises. The locking block 403 can slide on the outer side of the outer fixed ring plate 101. At this time, the return spring 405 is in a compressed state.
[0027] Then move the connecting long frame 401, so that the locking block 403 enters the locking notch 1011, so that the first connecting piece 1 and the outer sleeve 3 will not move horizontally easily, achieving the effect of locking the outer sleeve 3 and improving the safety during use.
[0028] When disassembling the first connecting piece 1 and the second connecting piece 2, lift the handle 406 upward, and the hook locking block 409 will be lifted synchronously, so that the locking block 403 leaves the locking notch 1011. Then rotate the outer sleeve 3 in the reverse direction to separate the first connecting piece 1 and the second connecting piece 2.
[0029] The working principle of the present utility model is as follows: The first connecting member 1 and the second connecting member 2 are butted. The hook lock block 409 in the locking assembly 4 contacts the outer fixed ring plate 101 and rises upward, causing the return spring 408 to be compressed. As the second connecting member 2 moves, the hook lock block 409 moves to the other end face of the outer fixed ring plate 101. At the same time, the handle 406 is lifted upward, causing the locking block 403 to rise. The locking block 403 can then slide on the outside of the outer fixed ring plate 101. At this time, the return spring 405 is in a compressed state. Then, the outer screw sleeve 3 is rotated, so that the inner connecting cylinder 103 can move on the outside of the first connecting member 1 and slowly enter the inside of the outer screw sleeve 3. At the same time, the inner connecting end cylinder 104 will enter the inside of the second connecting member 2 until the sealing gasket 105 contacts the outer screw sleeve 3, enabling a certain degree of sealing between the first connecting member 1 and the second connecting member 2, facilitating the flow of the coolant. It should be noted that after the inner connecting cylinder 103 enters the outer screw sleeve 3, one end of the inner connecting cylinder 103 is flush with one end of the first connecting member 1. At this time, the return spring 102 is in an extended state, providing a pulling force to the inner connecting cylinder 103 to prevent the inner connecting cylinder 103 from loosening;
[0030] Then, the movable connecting long frame 401 is moved so that the locking block 403 is inserted into the locking opening 1011, thereby preventing the first connecting member 1 and the outer screw sleeve 3 from easily moving laterally, achieving the effect of locking the outer screw sleeve 3 and improving the safety during use;
[0031] When disassembling the first connecting member 1 and the second connecting member 2, the handle 406 is lifted upward, and the hook lock block 409 will be lifted synchronously, causing the locking block 403 to leave the locking opening 1011. Then, the outer screw sleeve 3 is rotated in the reverse direction to separate the first connecting member 1 and the second connecting member 2. This can reduce the parts required for on-site connection and improve the installation and disassembly efficiency.
[0032] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
